Hi ,

I have problem in passing array to python function.
Please help me passing array to python function.

Here is my  'C' program
-----------------------

void  RECEIVE_IL_STATE_S( int Instance , int vital_data[5])
{
    PyObject*arglist;
    PyObject* ret;
    PyObject* mylist;
    int count;
    
    mylist = PyList_New(5);
    for (count=0; count< 5; count++) {
          myint = PyInt_FromLong(vital_data[count]);
          PyList_Append(mylist,myint); 
    }
    arglist = Py_BuildValue("O", mylist);
    ret = PyEval_CallObject(my_callback , arglist);
    Py_DECREF(arglist);
    Py_DECREF(ret);
} 

Here is my Python program
-------------------------

G_Logfile          = None

def TestFunction(a):
    G_Logfile = open('Pytestfile.txt', 'w')
    G_Logfile.write("%d \n"% a[0])
    G_Logfile.write("%d \n"% a[1])
    G_Logfile.close


Cheers,

Praveen.
